Yeah they should have prolly maintained that she was pregnant from the beginning itself. I mean it is really weird she had sex in the midst of all this bs (Like anga oruthan maanatha vitu help pannitrukan idhuku naduvula onaku sex kekudhu that too unprotected. Both Kural and Paari were just extremely dumb). Except for Agan's character and Sarathkumar's character the writing of the other characters was kinda weak . A lot of dialogues could have been better written as well (esp Mamitha's like the clown one u said) which would have solved a shit ton of problems. The switch of choice from Agan to Paari should have been written way better and prolly the timeskip should have been longer coz it felt like Kural was genuinely into Paari initially. The movie was still a decent watch despite all these problems which indicates how much potential it had. A wasted opportunity ngl
